Tesla’s Musk Needs to Find His Mary Barra

I’m not going to win any popularity contests criticizing Elon Musk’s recent efforts to aid the rescue of a dozen young soccer players in Thailand. Like a real-life Tony Stark, ​the entrepreneur and father of five boys commissioned engineers to work up a kiddie submarine and then delivered it to Tham Luang cave where the boys were trapped.

In the end, the boys didn’t need the Musk MiniSub. And back at his own business empire, Mr. Musk is spread alarmingly thin.
